IVESLEY COULTER, OF PITTSBURG, PENNSYLVANIA.

SASH FASTENER.

SPECIFICATION forming part of Letters Patent No. 451,388, dated April 28, 1891.

Application filed December 23 1890. Serial No. 375,623. (No model.)

To all whom it may concern.-

Be it known that I, WEsLnY CoULTER, of

Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain newand useful Improvements in Sash-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Myinvention relates to an improvement in sash-locks; and it consists in the construction and arrangement of parts, which will be fully described hereinafter.

The object of my invention is to provide a sash-lock of the construction hereinafter described, which is composed of two pivoted latches, a reciprocating slide for operating the latches simultaneously and thus causing them to either engage or disengage the sashes.

Figure 1 is a perspective of a sash-lock which embodies my invention, being partly shown in section. Fig. 2 is a detached perspective View of the bead.

A indicates ametallic plate, which is placed in a horizontal position in the frame of the window at the junction of the upper and lower sashes. Extending inward from this plate A are the ears B, upon which are pivoted at their inner adjacent ends the latches O D. The latch C is pivoted at the-point E, which is at the outer portion of its inner end, and extending laterally from the said latch inside of its pivoted point is a projection F. Extending laterally from the latch D at the outer portion of its inner end is a projection G, and this projection is outside of the pivotal point H of the said latch. Each of the latches is made substantially L-shaped, as shown, and their laterally-extending portions I pass through the openings J, which are made transversely through the plate A.

Passing through the outer end of the plate A is an operating-bolt K, which is provided with a milled enlarged outer end, by means of which the bolt is revolved. The inner end of the bolt K is provided with an angular portion upon which is placeda cam L, and the inner extremity of the bolt is screw-threaded for the reception of anut. Placed between this nut and the cam is a washer M. Extending along the inner side of the plate A is a reciprocating or sliding bar N, which has its outer end provided with an opening to receive the said cam, and these parts are held in place by means of the washer, which is placed over the cam and the adjacent end of the reciprocating or sliding bar. When the bolt K is revolved, the bar is made to move back and forth by means of the cam, as will be readily understood. Extending laterally from the sliding bar is a projection O, which is provided with a slot in which the projection upon the latch D is placed, and the inner end of the said reciprocating bar is provided with a slot P, in which is placed the projection upon the other latch O. For the purpose of limiting the distance that the bolt shall be revolved and thereby the back and forth movement of the said bar, a projection Q upon the plate A engages notches made in the edge of the outer end of the bar. By means of this construction it will be seen that when the bar is forced inward the latches are thrown back into an opening made in the window-casing, as shown in Fig. 1, owing to the fact that the projections upon the latches are upon opposite sides of their pivotal points, as before described.

The laterally-extending portions of the latches will engage a rack-bar, which is placed upon the adjacent edges of the upper and lower sashes, or the edges of the sashes themselves maybe provided with recesses or notches into which the catches will extend. These racks or series of notches willbe made to extend along the adjacent edges of the sashes any desired distance, so that they can be locked down or partially raised or lowered, as desired.

It will be seen from the above description that a very simple contrivance is produced for locking the upper and lower sashes, and which is very cheap to manufacture.

Having thus described my invention, I claim 1. In a sash-lock, the combination of a plate, a latch pivoted thereon having a projection, a reciprocating bar which engages the projection and which has an opening in one end, and an operating-bolt which is provided with ICO acannvithin the opening of the bar,combined to operate substantially as set forth.

2. In asash-loek, the combination of a plate, two latches having their inner and adjacent ends pivoted thereon and their opposite ends provided with laterally-extending portions which engage Window-sashes, and laterallyextending projections upon the latches at opposite sides of their pivotal points, and a reeiprocating bar which engages the projec- 1o tions, substantially as shown.

In testimony whereof I affix my signature in presence of two witnesses.
